System and method for virtually tracking a surgical tool on a movable display

Abstract

The invention comprises a virtual window system that creates a visual coherency between the image of the patient and his or her anatomy and the patient by aligning the image of the patient anatomy on the display to the patient and presenting the image to the user that feels is if the user is looking directly into the patient through the display. The invention is designed to also display medical devices, such as a minimally invasive tool. The system substantially unifies the coordinate systems of the patient, the medical device, the display, and the physician's hands. The invention creates a visual coherency between the motion of the medical device in the image and the motion of the physician's hands manipulating the device. This invention also creates a visual coherency between the motion of the image in the display and display.

Description

CROSS-REFERENCE[0001]This application claims the benefit of U.S. Provisional Application No. 61 / 535,753, filed Sep. 16, 2011; U.S. Provisional Application No. 61 / 585,580 filed on Jan. 11, 2012; and U.S. Provisional Application No. 61 / 615,141 filed on Mar. 23, 2012, all of which are incorporated herein by reference in their entirety.BACKGROUND OF THE INVENTION1. Field of the Invention[0002]The invention relates generally to the diagnosis and treatment of disorders using minimally invasive techniques. In many minimally invasive procedures very small devices are manipulated within the patient's body under visualization from a live imaging source like ultrasound, fluoroscopy, or endoscopy. Live imaging in a minimally invasive procedure may be supplemented or replaced by displaying the position of a sensored medical device within a stored image of the patient anatomy.[0003]Many minimally invasive catheter procedures are conducted in expensive hospital settings by specialized physicians. ...

AI Technical Summary

Benefits of technology

This patent describes a virtual window system that creates a realistic view of a patient's body through a display. The system aligns the image of the patient's anatomy with the user's hands, creating a sense of looking directly into the patient. The system also aligns the motion of the user's hands with the motion of the medical device being used, creating a seamless experience for the user. The system also improves ergonomics and allows for easy positioning of the display. It includes techniques to track the position of the display and the patient, ensuring constant alignment. Overall, the system provides a more realistic and immersive view of the surgical procedure, improving the user's ability to perform the procedure.

Problems solved by technology

For instance, moving the display with a unity ratio may cause the display to interfere with other equipment during some portion of the procedure or may make the screen difficult to view.
